The Football Association has written to Queens Park Rangers requesting their observations about a tweet from the club's new owner, Tony Fernandes, on Sunday in which he branded Michael Oliver, the referee, "blind".

Although it is understood that the letter is intended to serve as a warning and no sanctions will be imposed, English football's ruling body is also examining comments Neil Warnock made about Oliver after QPR's controverisal 1-1 draw with Aston Villa at Loftus Road on Sunday and may yet charge the home manager with bringing the game into disrepute.

During the game Richard Dunne's injury-time own goal secured Warnock's by then 10-man team a point after they had fallen behind to a rather soft-looking Barry Bannan penalty and then seen Villa's Alan Hutton get away with apparently twice handling the ball in the area.

While Warnock and Fernandes fumed, Shaun Wright-Phillips was, at least, revelling in his new life in west London. The 29-year-old former England winger, one of a number of signings made by Warnock after Fernandes bought the club late last month, has impressed since his transfer deadline day move from Manchester City and is not only relishing playing regular first-team football but no longer "hurting inside".

"I am loving it and I think we're gelling quite well as a team," he said. "I go home happy and I look forward to training and the game again. I know how to prepare myself again; if you don't know when you are going to play, how do you focus on a game?

"That's part of football, though, and if you are going to be at a big club you have to deal with it. I had it at Chelsea and Manchester City and you know it's not about yourself, it's a team game.

"If you are hurting inside, you can't really show it because you want the team to do well. I was hurting inside because I am a footballer and I want to play but that's just the way it goes sometimes."

Villa's manager, Alex McLeish, acknowledged that his team had considerable scope for improvement. "Our touch and passing was very poor up until half-time and thankfully we got a grip in the second half," he said.

Asked about Bannan, he said: "I don't want to put too much pressure on the young players. The expectations at a club like Villa are that we should be higher up the table, winning games.

"I will take the pressure off the young players. We have to try and make progress along the way, as steadily as possible. Barry has shown some bright moments in different positions."
